Embodiment Construction
[0043]A de-icing arrangement for de-icing a structural element comprises at least one actuator for removing ice from the structural element, a capacitive storage bank and a control unit arranged to control discharge of the capacitive storage bank to provide an excitation pulse to the at least one electromagnetic actuator so as to force the actuator to apply a mechanical force on the structural element so as to provide a chock in the structural element. This may result in removal of ice from the structural element. The actuator is arranged to expand in at least one direction when fed with the excitation pulse. The actuator is arranged in relation to the structural element so that mechanical force caused by the expansion on the structural element will be applied to the structure element.
[0044]The capacitive storage bank comprises a plurality of selectable capacitors of different capacitance. The control unit is arranged to select at least one capacitor for charging having a total capa...
